From what Guth with Sumitomo Rubber said, I wondered if high negative camber was causing the problem, but I still don't see how that caused the groove down the center of the LF tread. And Guth's statement that "Any type of shoulder wear could indicate inadequate air pressure and/or incorrect camber" caught my attention. I'm pretty sure shoulder wear is a fact of life with street cars like ours.

So I have noticed some heavier inside wear on tracks that have several long loaded corners at higher negative camber settings. I was digging through some tire pictures and I do have one where my left front was as worn on the inside as it was on the outside. I just attributed it to high static camber putting it up on the inside edge under load. Never had the wear you show though. Though I settled on 35psi hot, I had run anywhere from 33-37psi with the 660's.
